Question

On a surface weather map, a low pressure center is associated with _____ and _____ air, while a high pressure center is associated with _____ and _____ air. A. divergence; sinking; convergence: rising B. convergence; sinking; divergence; rising C. divergence rising convergence, sinking D. Convergence rising; divergence; sinking Which of the following is true concerning solar angle? A. At Lubbock, the solar angle is higher on January 1 than on July 1. B. The solar angle affects beam spreading but not beam depletion. C. Neglecting the effect of clouds or other factor, a low solar angle at some location means less beam spreading and more intense heating of the earth's surface. D. Neglecting the effect of clouds or other factor, a high solar angle at some location means less beam spreading and more intense heating of the earth's surface.

Explanation / Answer

Air converges and rises up while at high pressure points air diverges and sinks down.

A. Solar angle at Lubbock is higher on July than January.

B. The solar angle affects Both beam spreading bu and beam depletion. Beam spreading increases with decrease of solar angle while Beam depletion increases with the increase of solar angle.

C. Beam spreading increases with decrease of soalr angle. Therefore low solar angle means high beam spreading.

D. High solar angle means less beam spreading and more intense heating.'

Therefore the correct choice is, D.
